Equipment

Long and short wave dual wavelength ultraviolet lamp, mainly used for the test samples in the ultraviolet wavelength radiation, stimulated conditions of luminescence, used to identify and distinguish gems, or to understand the characteristics of gem optimization treatment, natural and synthetic, or after some filling treatment.

Technical parameters:

LW=365nm SW=253.7nm dual wavelength;

Special filter visible filter, and coating protection, excellent stability;

Switching between long and short wave dual solid state relays ensures the accuracy of wavelength selection.

The light source box is separated from the sample observation room to facilitate the observation of large size samples.

Protected by protective glass;

Large black box and curtain type take lofting window;

Optional wavelength discrimination board for accurate determination of the wavelength in use.
